This invention relates particularly to a double hung window sashconstruction wherein the individual sash may be opened inwardly for moreeffective Ventilation, or to facilitate the lcleaning of said'sash.

An object of the invention is to provide in a window having slidingsashes therein,

means whereby either onev or both'of the sash may be entirely removedfrom the inside of the window opening, or the said sash .may be swunginto any desired angular position relative to the opening. p

@ther objects and advantages are to provide a duoble hung window sashconstruction that will be superior in point of simplicity,

inexpensiveness of construction, positiveness of operation, and facilityand convenience in use and general efficiency.

in this specification and the annexed drawconsidered to be the best, butit is to be under stood that the invention is not limited to such form,because it may be embodied in other forms; andit is also to beunderstood that in and by the claims following the description, it isdesired to cover the invention in whatsoever form it may be embodied.

Fig. 6 is a sectional detail view taken on the line 6-6 of Fig. 1. Y

ln detail the construction illustrated in the drawing comprises avwindow lframe formed of theside jambs 1 on opposite sides thereof, theoverhead lintel 2, the stool and Vto slide past each other in a verticaldirection within the frame, the said saslies being separated" by aparting bead 9 confined in a groove 10 in the said jambs and lintel. Astop strip 11 extends around the inside of the edge of the jambe andlintel, and a similar stop 12 around the outside of the frame, each ofsaid stops lying parallel to the parting bead to provide guideways iiiwhich the opposite side edges of the window sash are free to slide. Asash pulley 13 is arranged adjacent the upper end of each sash track,and a sash cord lLlvmounted on the side of each of the saslies passesaround the sash pulley, and the vided with a sash Weight thereon mounteding, the invention is illustrated in the forml construction thus fardescribed,l is conventional to what is known as a double hung slidingwindow.

In adapting my invention to a double hung sliding sash, I cut away aportion of the face of each jamb, facing the window opening, in ahorizontal direction from the edge of the jamb on the inner side thereofto a point substantially flush with the outerside ofthe parting bead,and in a vertical direction for a distance greater than' the height ofthe lower sash. Each of the opposite jambs 1 are out away as at 16,-inlike amount, and the cut away portion extends from a point slightlyabove the stool 3, to a point above the upper stileof the lower sash.The cut away portion in each jamb provides a shoulder 17 at the bottomedge thereof, and a shoulder in alignment and the width of the saidchannel is equal to the depth of the cut away portion 16 so that oneexposed side edge of the said channel lies flush with the face of thesash slideway. Each channel guideway 19 is provided with a slide member2() therein, said slide member having a pin 21 extending laterallytherethrough, and the ends of said pin are conned in slots 22 cut in theopposite side walls of the channel. The length rof the slots 22regulates the length of movement of the pin 21 therein, and therebydetermines the amount of sliding movement which the slide 2O may haverelative to the channel 19. The slide is provided with an extension -23thereon which conforms in contour in cross section to the slide 20, vtheextension 23 being pivoted at 24, to the slide 2O so that the extensionmay pivot or swing on a horizontal `plane about a vertical axis relativeto the slide 20. Both the slide 2O and extension 23 do not projectbeyond the open upperk side of the channel 19. A filler piece 25 isadaptved to be fitted into the cut away portion 16 of the jamb, and tofill out the entire area of the cut away portion between the spacedchannels 19 and the vertical front and rear edges of the said cut awayportion. r1`he opposite ends of the filler piece are securedto theextension members 23 on the opposite slides. The inside face of thefiller piece vis provided with the parting bead 9 and stop 1'1 thereon,to form a continuation of the V'same parts which are a permanent part ofthe window jamb. lVhen the filler piece is in a'position `withthe beadand stop thereon in alignment with the permanent bead and s'top on thewindow jamb, a slideway is formed for the lower sash which permits saidsash to be moved upwardly into a position opposite the upper sash, or tobe locked into a per- Y manent position in the lower part of the windowframe. i

'If it be assumed that the Vsas'hes werenot in 'the window frame, thefiller pieces on the' opposite side jambs could'be moved inwardly towardthe interior of the window frame and then swung in a horizontal positionthrough an arc of 90, to lie flat against the faces of the casing on theinside of the window frame. The slide 20 is 'permitted to travel towardone edge of the channel guide 19 until the pivot'24 is in an exposedposition.

The extension 23 on the slide will then be free to swing backwardlytoward 'the casing onthe frame. Assuming the filler piece to vbe in itsnormal closed position and the sash installed lin operating position in'the window frame,'the first operation necessary in orderfor'the'operator to move the lower sash out of the window frame,'wouldbe to slide said lower sash upwardly aslight dis- 'tance above the faceof thesill 3 so that the -*upper and lower stiles vof the said bottomsition, the sash is out of the frame and maybe manipulated in anysuitable manner for either ventilation purposes, or to permit cleaningof 'the glass, the insertion of a new pane of glass, or the painting ofthe outside of the said sash, from the interior of the room. y v

Alfter 'the lower sash has been removed from the frame in the mannerhereinabove set forth, the upper sash may be slid downwardly to registerwith Athe opening provided in :the opposite sides vof 4the jamb, and thesaid upper sash may be bodily removed from the window frame andmanipulated as desired. The upper sash may be returned from a 'positionremote from the window frame to the frame by merely shoving it into theopening until'opposite sides of the said sash lie inthe guideway forsaid sash. The lower sash, however, is moved into sliding position inthe window frame by arranging said sash in a position which issubstantially parallel to the position in which it is vto be operated,then swinging Vthe 'filler pieces 25 around so that the guidewaystherein engage the oppositesides of thesash, and then the sash andfiller pieces are forced inwardly into the window vframe until theguideways in the opposite sides of the filler `pieces register with thecorresponding 'permanent guideways in '-25 in position inthe jamb,although it is clearly within'the scope o'fthis invention to providelocking members on the frame which C may be utilized to hold the saidfiller pieces ina fixed position, until such'time as it would be desiredto move the filler pieces outwardly'in orderto remove a'sash from thewindow frame.

For the purpose of illustration, a spring plunger type'of lock 26 isshown inthe drawing, and especially in Fig. 6.

It is to be noted that by the removal of the fillers and the stopsandbeads'thereon in the aforementioned manner. the usual holes in thecasing provided for the removal of the sash weights are rendered easilyaccessible without necessitating the prying olf of the stops.unfastening and removal of the stops before the sash weights can beremoved, frequently mars the lcasing and 'is in general, inconvement.This inconvenience is entirely obviated by Imy structure.

In the usual type of windows the It is also to be noted that instead ofcutting away the jamb, a metal filler plate of suitable thickness may besupported on the extension members 23 of the slides The metal plateswould slide on the usual jamb surface and would carry sections of thestops and beads thereon. In this instance the edges of the sashes wouldbe shaved off to a degree to be slidable between the opposed metal l@filler plates.

I-Iaving thus described this invention, what I claim and desire tosecure by Letters Patent is:

l. A window including a frame having vertical ledges to afford runways;sashes reciprocating in said runways; telescoping means on the oppositesides of the window to removably support opposed portions of saidledges; portions of said telescoping means being hinged to swing theremovable ledge portions into and out of way position, after the saidledges are simultaneously removed from the runway.

2. A window including a frame formed 75 with runways; sashesreciprocating in said runways; a section of one side of each runwaybeing removable to afford clearance for the removal of said sashes;telescoping connecting means between each of said remov- 3 able sectionsand the frame to allow the bodily withdrawals of said sections with oneof the window sashes from the runways; a movable sectional supportforming the movable part of said telescoping connection, the sectionsthereof being pivotally secured to each other; the said removablesections of the runway side being mounted on the said pivoted supportsections whereby they are swingable outwardly away from the respectivesides of the sash to allow the free swinging of the window sash.

3. In a window the combination with a casing delining a window opening,upper and lower sash members. inner and outer stops and beads betweenthe stops to form runways for the sash members; of opposed sections inthe inner runways being removable inwardly with respect to the wall inwhich the window casing is mounted; a channel trackway secured to thecasing opposite each end of each removable section, so as to be flushwith the bottom of the respective runways; a slide member telescopedinto each channel with freedom of limited sliding movement -1 inwardlyfrom the windowopenlng; a pivoted ele-ment on each of said slide memberson which the said removable sections are mounted7 whereby the saidsections are swingable in an out of way position relatively to said '33window opening.

In testimony whereof, I have hereunto set my hand at San Francisco,California, this 18th day of April 1931.
